An arc AB subtends an angle of 2.4 radians at the center O of a circle with radius 50 cm. Find the area and perimeter of sector AOB.
The bottom of a pendulum traces an arc 3 feet in length when the pendulum swings through an angle of ½ radian. What is the number of feet in the length of the pendulum?
Answer:
a. i. 3000 cm² ii. 220 cm b. 6 feet
Step-by-step explanation:
A. i. The area of the sector AOB is A = ¹/₂r²θ where r = radius of circle = 50 cm and θ = angle subtended at the center of the circle by the sector in radians = 2.4 radians.
So, A = ¹/₂r²θ
= ¹/₂(50 cm)² × 2.4 rad
= ¹/₂ × 2500 cm² × 2.4 rad
= 1250 cm² × 2.4 rad
= 3000 cm²
ii. The perimeter of the sector is P = 2r + rθ = (2 + θ)r
substituting r and θ, we have
P = (2 + θ)r
= (2 + 2.4) × 50 cm
= 4.4 × 50 cm
= 220 cm
B. Since length of an arc L = rθ where r = radius = length of pendulum and θ = angle swept by pendulum = ½ radian and length of the arc swept = 3 feet, the radius is
r = L/θ
= 3 feet ÷ ½ rad
= 3 × 2
= 6 feet
An angle measures 48° more than the measure of its complementary angle. What is the
measure of each angle?
Answer:
The angles measure 21 degrees and 69 degrees.
Step-by-step explanation:
Complementary angles have a sum of 90 degrees when added together.
Let's call the complementary angle x. We can write the angle that we're looking for as in terms of x as x + 48.
Since these angles must sum to 90 we can write the equation and solve:
x + x + 48 = 90
2x + 48 = 90
2x + 48 - 48 = 90 - 48
2x = 42
x = 21
x + 48 = 69
21 degrees and 69 degrees.
Answer:
69° and 21° is the answer.
Consider the following linear equations. y = 2x + 5 y = 2x - 3 Which statement below if True?

Needed A.S.A.P thank you very much!!
Answer:
Option B is correct
Step-by-step explanation:
The equation of a straight line is given as;
y = mx + b
where m is the slope and b is y-intercept
Let’s evaluate the options one after the other;
A. This is wrong as they both have same slope of 2
C. The y-intercepts are not the same
One is 5, the other is -3
D. This is wrong, the line cannot be the same
Option B is correct

A salesman drove from his home to a nearby city at an average speed of 40 mi/h. He returned home at an average speed of 50 mi/h. What was his average speed for the entire trip?
Answer:
44.44 mph
Step-by-step explanation:
[tex]speed = \frac{distance}{time} = \frac{distanceTo + distanceFrom}{time1 + time2} = \frac{2d}{\frac{d}{40} + \frac{d}{50} }[/tex]
= [tex]\frac{2d}{\frac{5d + 4d}{200} } = \frac{2d}{\frac{9d}{200} }[/tex]
= 2d * [tex]\frac{200}{9d}[/tex]
= 400 / 9
= 44.44
Answer:
44.4 miles per hour
Step-by-step explanation:
d = the distance between cities
t 1= the time from home to the city
t 1 = the time . from the city to home
2d/t1 + t2 = 2d/ d/40 + d/50
=2d/5d+4d =2d/9d
divide both sides by 200
=2d * 200/9d =400/9
= 44.4

Given the replacement set:
b={4.4, 5.4, 6.4}
Which inequality is true?
b−6>10.4
b+6<10.4
b−8≥12.4
b+8≥12.4
Answer:
b+8≥12.4
Step-by-step explanation:
Here, we want to select the correct option
From what we have here;
b ≥12.4-8
b ≥ 4.4
Looking at the range of values in the set
We can see that the smallest of values is 4.4
This tells exactly the correctness of the last option as the values of b are 4.4 or greater

Answer: The float committee made a scale model of their float before they started construction. The float committee used the scale 1 inch : 3 Feet to create their model. The actual float will be 18 feet long.
So this being said.
Step-by-step explanation:
Your answer should be 6 inches. I hope this helps!
The length of the scale model of the float is required.
The length of the scale model would be 6 inches.
Scale diagramsIt is given that one inch of the scale model of the float is three feet of the actual float.
[tex]1\ \text{inch}=3\ \text{feet}[/tex]
Now, what 1 feet of the float represents in the scale model is required.
So, we divide both sides by 3

In 1978, the Social Security and Medicare rate combined was 6.05%, up to $17,700 earned. Express the Social Security tax s(x) for 1978 as a piecewise function. Ten years later, the percent had increased to 7.51% and the maximum taxable income had increased to $45,000. Express the Social Security tax s(x) for 1988 as a piecewise function. If a person earned $50,000 in 1978, and $50,000 in 1988, what was the difference in the Social Security and Medicare taxes paid?
Answer:
Step-by-step explanation:
From the given question:
a) The piecewise function for the Social Security tax s(x) is expressed as:
s(x) = x * 6.05% when x < $17,700
The 6.05% of the given amount is:
= (6.05/100) * 17700
= 1070.85
s(x) = 1070.85 when x ≥ $17,700
b) Ten years later, i.e. 1988; the percentage had increased to 7.51% & maximum taxable income also increased to $45000
The piecewise function for the Social Security tax s(x) is expressed as:
s(x) = x * 7.51% when x < $45,000
The 7.51% of the given amount is:
= (7.51/100) * 45000
= 3379.5
s(x) = 3379.5 when x ≥ $45,500
c) The difference in the Social Security and Medicare taxes paid is as follows:
In 1978, s(x) = 1070.85 when x ≥ $17,700
In 1988, s(x) = 3379.5 when x ≥ $45,500
The difference in the Social Security and Medicare taxes paid = $3379.5 - $1070.85
The difference in the Social Security and Medicare taxes paid = $2308.65
In 1988 $ 1,578.65 less was paid than in 1978.
Given that in 1978, the Social Security and Medicare rate combined was 6.05%, up to $ 17,700 earned, while ten years later, the percent had increased to 7.51% and the maximum taxable income had increased to $ 45,000, to determine, if a person earned $ 50,000 in 1978, and $ 50,000 in 1988, what was the difference in the Social Security and Medicare taxes paid, the following calculations must be performed:
(50,000 - 17,700) x 0.0605 = year 1978 1,954.15 = year 1978 (50,000 - 45,000) x 0.0751 = year 1988 375.50 = year 1988 year 1978 - year 1988 = 1,578.65
Therefore, in 1988 $ 1,578.65 less was paid than in 1978.

What is the smallest perfect square that can be written as the sum of three different prime numbers?
Answer:
19 is the smallest prime number that is the sum of three different prime number.
Step-by-step explanation:
To find this:
2 is the only even prime number and other prime numbers are odd
adding any two prime number always gives even number.
so the least numbers that are required to do is 3,5 and 7; their sum is 15
so any prine number less than 15 is not possible for this question
so, the next prime number is 17
17 minus any other prime no less 17 are13,11,7.5.3,2 give the number that 4,6,10,12,14,15 which are not sum of any two different prime numbers
so the answer is 19=11+5+3.
The smallest perfect square that can be written as the sum of 3 different prime numbers is; 16.
Prime numbers are numbers that can be divided by only themselves and 1.Now, we want to find the smallest perfect square that can be written as the sum of three prime numbers and so let us list the perfect squares from 1 to 30.
They are; 4, 9, 16, 25.
Now, for 4; sum of 3 different prime numbers cannot work here because it will give us 1 + 2 + 3 = 5.For 9; sum of 3 different prime numbers cannot work here because it will give us 2 + 3 + 5 = 10.For 16; sum of 3 different prime numbers will work here because it will give us 2 + 3 + 11 = 16Thus, the smallest perfect square that can be written as the sum of 3 different prime numbers is 16.Read more at; https://brainly.in/question/17539113
